What is the .TPU File Extension?

.TPU File Extension Description:

The file extension TPU is categorized as a developer file format created by Turbo Pascal, a software development system that includes a compiler and an IDE (Integrated Development Environment) for the Pascal programming language. TPU stands for Turbo Pascal Unit, the concept introduced by Borland for use as external function libraries, a little more high level than the object files used in languages such as C. As a result, programmers are able to define what will be visible outside the unit and what is not.

Turbo Pascal's syntax for the TPU file extension were borrowed from UCSD Pascal, a portable, highly-machine independent operating system which uses notable file extensions including separately compilable "units" and "string" types. With Turbo Pascal's earlier versions that ran on computers with low specifications, the complexity of the package did not demand it. However, with the new ability of programs to generate large EXE files, separate compilation is needed to overpower the complexity.

When Turbo Pascal compiles a unit, the resulting file is written to a file with the .tpu file extension. But if the compiler cannot find the requested unit, it then searches the list of given directories to find the files with the .tpu file extension with the same root name as the unit. This is because the TPU file extension uses the full name of the unit, not just the first 8 characters. Turbo Pascal then checks the library first, and the search stops if it finds the unit.

The file with the .tpu file extension is an example of a compiled file in which the file being compiled is translated into a text written in a particular computer language (known as the source language) into another computer language (knows as the target language). The input is called the source code while the output will be the object code. Usually the output has a form that is suitable for processing by other program.

In order to create your file with the .tpu file extension, first you need to create a file with the .pas file extension that contains all the program code for the library unit. Then compile the file with the .pas file extension to create a TPU machine code version of the library. The library's name can now be finally included in the list of the Turbo Pascal programs.

To compile the file with the .tpu file extension, choose a destination for the file that you created which will become the machine code version of the library. To use the library unit, include the unit's name in the "uses" line at the top of any program that needs access to your library.
